From 1960 to 1963, Garraway called the ship home. Based out of Key West, The Marlin was used to train other subs, ships and aircraft on sub detection.

It was a cramped lifestyle, to say the least.

"It was tight," Garraway said. "It's a third the size of the old World War 2 boats. Instead of nine watertight compartments, they had only three. This is the control room. This is was where everything was ordered. You would dive. You would surface from here. You would order a snorkeling."

Just behind the the control room was the radio room, where communications were sent and received.

"Three people slept in this compartment," Garraway said. "The captain, the exec, and the chief of the boat."

The machinery space was where the engines and generators powered it all.

"One man stood his watches in here," Garraway explained. "So for three years, this is where I stood my watches."

John Foose was part of the top-side gang. One of his duties was crawling under the deck, looking for looses pipes. One time, he got stuck.

"I was able to take my arm and get it just around in front of me to get to my pack of cigarettes, and I stood there and smoked a couple of cigarettes and finally calmed down enough to get back out," Foose said.

Regardless of what the memory is, the old crew members agree on one thing.

"This is history," John Delihanty said. "When this is gone, we don't have anything to remember."
